Html 引导菜单显示绿色ul箭头

我试图创建一个引导菜单，但当我从引导网站将代码添加到我的cs html页面时，它不会正确显示在我的页面中。我看到菜单上有绿色的小箭头。我的项目中有java脚本和引导脚本。有没有办法去掉那些绿色的小箭头，让菜单看起来更像引导示例

您要查找的元素很可能在jquery ui css中。类似于

arrow\u right\u spearmint.png

。注释掉它或给它一个内联值null应该可以解决这个问题

检查检查器（右键单击箭头并选择inspect element）以查看绿色箭头的附加内容。它不在DOM中，所以它必须是应用于那些列表项的：before或：after css规则。我从url删除了arrow_right_spearmint.png:.nav li{background:url（）不重复中左；}非常感谢。
